This paper deals with two issues concerning constructive robbery: first, whether the prototype of robbery can universally apply to constructive robbery; second, only when the degree of the forcible means employed by the larcenists or forcible takers is in consistence with that of robbery can they be punished with offense of robbery. With regard to the second issue, the Interpretation No. 630 of the Judicial Yuan generally agrees with the ideas presented in this paper. This paper also presents a further discussion toward the meaning of 'rendering resistance impossible.'
